If OLED is a wet noodle or like a screen for a window, curving it is no where near enough strength to hold itself up.
Single layer OLED with its stacks and color filter wrgb might be as thin as LCD layers?
No, the OLED including substrate, drive transistors, OLED layer, WRGB color filter and protective glass is probably about the same thickness as the LED/LCD including substrate, drive transistors, LCD layer, WRGB color filter and protective glass.
But then the LED/LCD has the LED backlight which is at least
that thick again (and quite a bit thicker in the case of direct lit). The backlight structure of an LED/LCD provides additional rigidity to the LCD panel itself which is unavailable to OLED.
The curve alone
does not hold OLED up. There is a plastic support sheet/structure that adds additional rigidity, so you have curved plastic + curved OLED. If the entire structure was composed the same way but flat, it would be too flexible. The plastic support structure can be made more rigid by adding ribs, thickness, etc... but all of this is going to add cost.
There is no
bezel on OLED (while LED/LCD needs a bezel, especially for edge-lit because that is where the LEDs are). Bezels add a great deal of structural integrity / rigidity. OLED could add
a bezel, but again, that would add cost.
